I'm new here, and I am a beginner in CFD...
I have installed Gambit 2.2.30, Fluent 6.3.26 and Hummbirdgrid with Exceed.
On top of that, I have CATIA V5R17 for the CAO.
My problem is that, when I make a CAO in CATIA, and when I try to import it in Gambit, the softwar crashes !
I don't understand why and how to figure it out !
I save the Catia file under "model" format and I try to import in CATIA V4, or STEP, or IGES ( after saving in .igs or .stp on Catia).
So I can't use my geometries to mesh it...
